Automatic Marine Debris Inspection

Aerospace, 2023
Plastic trash can be found anywhere, around the marina, beaches, and coastal areas in recent times. This study proposes a trash dataset called HAIDA and a trash detector that uses a YOLOv4-based object detection algorithm to monitor coastal trash pollution efficiently.

Life cycle environmental assessment of marine debris and post-consumer waste plastics into asphalt pavements

Cleaner Environmental Systems
This study evaluates locally adapted recycling strategies for marine derelict fishing gear (DFG) and post-consumer waste (PCW) plastics in Hawaiʻi using a life cycle assessment (LCA) framework. Comparative cradle-to-gate LCAs were conducted to assess the

Collection of Marine Debris by Jointly Using UAV-UUV With GUI for Simple Operation

IEEE Access, 2021
In recent years, floating debris in the sea has damaged the environment and harmed wildlife. Systems for collecting floating marine debris in the open ocean by installing a huge net or using a vacuum device have been proposed. However, to the best of our

Silicified Wood‐Inspired, High‐Strength Fire‐Resistant Chitin‐Based Aerogels for Sustainable High‐Temperature Thermal Insulation

Advanced Functional Materials, EarlyView.
Inspired by natural silicified wood, a biomimetic mineralized chitin‐derived aerogel is constructed. It can withstand 81 000 times its own weight, and its backside temperature is 130.4°C after exposure to ∼1300°C butane flame for 600 s, exhibiting high‐strength, fire‐resistance, and super thermal‐insulation properties.

Rise velocity of small polyolefin plastics in a seawater tank exposed to natural conditions in Hawai’i

Environmental Research Communications
Floating plastic is ubiquitous at the ocean surface, but the transport mechanisms associated with the type of particle and the effect of environmental parameters, including the presence of a biofilm on the polymers, are very limited.

Marine Debris Survey Manual [PDF]

, 1992
Over the last several years, concern has increased about the amount of man-made materials lost or discarded at sea and the potential impacts to the environment. The scope of the problem depends on the amounts and types of debris.

Micro- and nanoplastic pollution of freshwater and wastewater treatment systems [PDF]

, 2017
Plastic waste is a widespread and persistent global challenge with negative impacts on the environment, economy, human health and aesthetics. Plastic pollution has been a focus of environmental research over the past few decades, particularly in relation
